Incorrectly sizing your infrared heater could lead to one of two unpleasant situations. The first situation involves you and your family shivering around a ridiculously undersized heater incapable of heating your room.

Correctly sizing your infrared heater means one thing -- pure comfort.

  1. Measure the length of the room using your tape measure.

  2. Measure the width of the room using your tape measure.

  5. Match the infrared heater's BTU to your room's square footage, knowing that it requires approximately 45 BTU to successfully heat 1 square foot of space. For instance, if you have a 1,000 square foot home, you need a heater capable of producing 23 BTU, because 23 multiplied by 45 equals 1045.
